What is happening to the rupee
The rupee fell to a record low of ₹90 per dollar on 3 December 2025. In October 2026, it came close to its record low of just under ₹97 per dollar. By then it was down nearly 7% for the year. On 7 October, the RBI raised its repo rate by 25 basis points to 5.50%. Then on 10 October, it opened a special window to help state-run oil companies buy dollars and brought in new rules for some currency trades. The rupee opened at about ₹95.76 per dollar on 12 October.
Why is it weak? Reports point to high crude prices, strong demand for dollars from importers and a firm dollar.
The simple idea
A weak rupee means one dollar costs more rupees. Imagine the rupee moves from ₹90 to ₹96 per dollar. A company that earns $1 in sales now gets ₹6 more for it. A company that must pay $1 for imports now pays ₹6 more. This is a made-up example to show the idea.
Who usually gains
IT companies: They earn in dollars and pay most costs in rupees. On 9 October 2026, the Nifty IT index rose 3.43% as the rupee stayed weak.
Pharma and textile exporters: They also earn in dollars, though some input costs may rise.
Specialty chemicals and auto exporters: Companies with strong export income, such as Bajaj Auto, benefit from dollar revenue.
Who usually loses
Oil marketing companies: Crude is bought in dollars, so their costs rise.
Importers: Anyone buying electronics, chemicals or machinery from abroad pays more.
Companies with dollar loans: Repaying costs more rupees.
The RBI's steps to protect the rupee also raised hedging costs for importers, and left some exporters with lower rupee earnings than they had expected.
What it means for you
A weak rupee is not good or bad for the whole market. It changes the picture for each sector.
Foreign investors earn in dollars. A falling rupee can reduce their returns, which is one reason they may sell Indian stocks.
Look at how much of a company's income and costs is in dollars before judging the effect.
